Problem with this although a good idea is there is no eco built around skilling items you can spawn them in and drop them as you wish. To put a value on skilling would require either a full wipe of the items from the entirety of the game or new items both of which would take immense time. But I think the idea of items providing bonuses whilst skilling would be quite interesting, possibly pets corresponding to skill being used to provide bonus xp + loot chance similiar to the way skilling gauntlets work on RS3. Nevertheless always good feedback.
